A833 input shaft diameter

So i spent the better part of 2 days trying to get this a833 mounted (behind a 360). I keep running into an issue where the input shaft will only get so far before binding. The crankshaft is a new forged eagle crank with a dorman pilot bushing in it. After further investigation, I've found that there is a raised edge on my input shaft about 1.5" from the end. An increase of .030" (for about 1") which stops it from entering the pilot bushing.
I cant find a spec for the input shaft diameter (its .747 at the end, bit .770 at the raised portion). I've noticed the pilot bushing in the crank is now a bit beat up. Something seems wrong with my setup as there is about 1" between the scattershield and transmission mounting tabs.

I'm at a loss because any pilot bushing or bearing is .750 I'd, and will not sit far enough into the clutch for the splines to mate.

My next move is to remove the engine again and try making everything outside the truck.
